Grimsby Magistrates' Court heard the attacks were uncovered by the deafening pig squeals following a covert investigation by Animal Equality which placed secret cameras inside Fir Tree Farm in Goxhill, North Lincolnshire.

The sickening footage uncovered the horrific abuse at the hands of the two men as they were hauled before the courts following a prosecution by the RSPCA, reports Grimsby Live.

Dr Toni Shephard, Director of Animal Equality UK, said: "We are pleased that two pig farm workers have admitted their disgusting attacks on the vulnerable animals in their care, revealed by our investigation.

"We thank the RSPCA for prosecuting this case so swiftly."

The two men both pleaded guilty to causing unnecessary suffering to protected animals.

Grogprkevs, of East Marsh Road, Goxhill, admitted abusing the pigs between April 10 and April 27, by causing unnecessary suffering through the infliction of blunt force trauma, physical violence and the inappropriate use of a pitchfork, when knowing that the act was likely to have this effect.

The case was adjourned at the request of the prosecution so a third defendant could appear in court.
